Siloxa-Tek 8500 Ready to Use - 1 Gallon Penetrating Concrete Sealer, Water and Salt Repellent. Clear, Water-Based DOT Approved Silane/Siloxane for Concrete, Brick, Masonry & Pavers

Years ago, I used Thompson water sealer. The product changed over time; was milky and waxy when applied. I tried this product instead and have used it twice. The first time was for my chimney, which would leak when hit with high winds and driving rain. It sealed superbly; no leaks *at all*, ever. Then I purchased more to seal a concrete pad, and some touch up the chimney just in case. It's very easy to apply with a simple pump sprayer and performs exactly as advertised. This product is a winner; hope they don't change a thing about it.

Using on concrete in a basement and it's pretty good so far. It was easy to apply and dried actually pretty fast. No issues with heavy paint/chem smell either. I barely even noticed any harsh smell at all while doing the section of the basement I've gotten to so far. I'll probably be buying another container or two either online or in person over time as I do the rest of the basement

This product was recommended to me by a friend who recently used it with good results. I used it to reseal my stamped concrete patio. It was formerly stained, which this cannot be used on, but all the stain and sealant was gone. It was easy to apply, dried clear as advertised, and clearly keeps water from penetrating the concrete. It has only been applied for a month or two and has only seen a few rains but no snow yet, so cannot speak to durability or longevity, but seems promising

Application was easy for a novice using a roller and went on even, covering my patio in two coats as instructed. So far has been good for water repellant and dirt cleanup, and did not change the color or sheen of my concrete. Would probably rate a 5 , just need to see how it goes after a few more months.

Recently ordered my second gallon jug of this awesome product. Sadly, I miscalculated how much I would need for my project and had to split it up over the course of a couple weeks, but the results are awesome. First time using a concrete sealer, this all in one solution makes it easy. Threw it in a sprayer and went to town on my garage and walkway. This second gallon is for the rest of my driveway. So far after a week of rain, the results are great! Water puddles up and bounces off the concrete.Now the first time I ordered this, it came in a product box and an Amazon box, which resulted to it leaking all over my brand new front porch which left a white stain mark due to poor delivery. I messages Amazon but nothing was done regarding this. Not the products fault as the delivery was to blame, but be careful and be sure to evenly spread once you apply. The packaging on the second gallon ordered was much better! Tightly packed in with more cardboard, I could tell they must have had issues with bad deliveries since mine. Glad to see it get fixed and will gladly recommend this product for future projects.

I have been using this product for the past 6 years on our concrete driveway & sidewalk to seal and protect from salt and road grime during Winter. It does a great job sealing the surface and water beads up on it like a newly waxed car. Application is easy. Just pour it into a garden sprayer, no mixing required. Sprays on evenly and flows out so minimal pooling occurs. Drys fairly quickly too. I will continue to use this product until we sell our house.

Had a new driveway and new sidewalk installed, and the installer recommended putting a sealant on it after letting the new concrete dry for 30 days. Dancing around fall leaves and rain, we were able to seal the new concrete using two methods. Used a roller for part of it and, because our tank sprayer broke we turned to a small hand-held bottle sprayer to finish up and it worked fine, although it took a little time. It has a viscosity close to water and sprays easily. Two coats, as recommended, appears to be important. We ordered one bottle, which was not enough to cover our entire driveway but was enough to cover a sidewalk. We liked the results enough so that we ordered more to complete the task. Water from rains bubbled up nicely for the first couple of months, which gave us an indication that we'd covered the entire targeted area. Neighbors liked the look. There was no color change to the concrete. It just makes an area look damp when it's sprayed on. Three fall months after its application, it's still doing its job and the driveway looks good.

Seals well. Easy to use. Good finish.
